There are different definitions for detecting Loss-Of-Signal (LOS) alarms in the ITU-T
G.775 and ETS 300233. The FALC56 covers all these standards. The LOS indication is
performed by generating an interrupt (if not masked) and activating a status bit.
Additionally a LOS status change interrupt is programmable by using register GCR.SCI.

Data Sheet
An alarm is generated if the incoming data stream has no pulses (no transitions) for a
certain number (N) of consecutive pulse periods. “No pulse” in the digital receive
interface means a logical zero on pins RDIP/RDIN/ROID. A pulse with an amplitude
less than Q dB below nominal is the criteria for “no pulse” in the analog receive
interface (LIM1.DRS = 0). The receive signal level Q is programmable by three control
